Pixellated Posterior Sampling of Point Spread Functions in Astronomical Images Open
We introduce a novel framework for upsampled Point Spread Function (PSF) modeling using pixel-level Bayesian inference. Accurate PSF characterization is critical for precision measurements in many fields including: weak lensing, astrometry…

Mind the Information Gap: Unveiling Detailed Morphologies of z 0.5-1.0 Galaxies with SLACS Strong Lenses and Data-Driven Analysis Open
We present new state-of-the-art lens models for strong gravitational lensing systems from the Sloan Lens ACS (SLACS) survey, developed within a Bayesian framework that employs high-dimensional (pixellated), data-driven priors for the backg…

Reconstruction libre de lentilles gravitationnelles de type galaxie-galaxie avec les machines à inférence récurentielle Open
Les lentilles gravitationnelles de type galaxie-galaxie se produisent lorsque la lumière d'une galaxie en arrière-plan est déviée par le champ gravitationnel d'une galaxie en avant-plan, formant des images multiples ou même des anneaux d'E…
